This is a most excellent place for technology news and articles.
Considering it was just meant to be a proof of concept and only fly once or twice I would say that 71 flights, a max altitude of 78 ft(24 m), and 10.6 miles or 17 kilometers of travel, not to mention all of the footage from its on board cameras, makes Ingenuity an astounding success.
I was amazed it could fly at all in the thin atmosphere of Mars.
I believe they took this into account when they designed the thing.
Absolutely, but until you fly a heli on Mars you don't know 100% if it will work.
